Solution and Explanation
It is given that \(72\) % of \(25\) students are good in mathematics.
Therefore,
Percentage of students who are not good in mathematics = \((100 - 72)\) %
= \(28\) %
∴Number of students who are not good in mathematics = \(\frac{28}{100}×25\)
= \(7\)
Thus, \(7\) students are not good in mathematics.
